Introduction to Jiale Hall: Jiale Hall was built during the Heshen period. The "Jialue Hall" plaque hanging in the hall is suspected to have been given to Heshen by Emperor Qianlong, but there is no signature or seal on the plaque. , so there is no way to confirm it, but Heshen left the "Jialetang Poetry Collection", which shows that it is the name of Heshen's house. During the period of Prince Gong, Jiale Hall was mainly used as a sacrificial place for the royal palace. It contained tablets for ancestors and gods, and was mainly used for shamanistic rituals.
